It is good news that the input lag is low. Hopefully it isn't some kind of fluke.
U2311HM or U2311H over IPS236V. The Dell has 4 USB 2.0 ports on the monitor. Very convenient if your rig is not as easily accessible or you could use the extra USB ports. They can power external HDDs.

Other than that and the USB ports I had mentioned? The ips236v has an ugly bezel that is not suitable for multiple monitor gaming. For multiple monitor gaming, the last thing you want is for the bezel to stand out. Plain and forgettable are key, unless you can find monitors with practically no bezel or no bezel (!), which would trump everything else.
No, it doesn't. I game and spend extra to acquire 1080p movies, and I find 8ms displays (U2311H, U2410, U2412M) satisfactory.
